With Insight, you can examine the performance of various business applications and their accompanying components and Tiers. For each Tier, the Tier area provides a slightly different performance perspective which reflects the differences between the Tiers. For each Tier, the graphs in the Tier area compare the performance of entities that are related to the Tier.
When you examine the response time, each graph breaks the response time down into the various Tier states to help identify the nature of the problem. This breakdown is also Tier-dependent.

The Insight Savvy for OS has the capability to compare server’s resource utilization by logical CPUs. Insight Savvy for OS enumerates in each time slice the list of logical CPUs that the server is working on and samples several key metrics per CPU.
The following table shows the available metrics.

The term logical CPU is platform specific and refers to the logical representation of a processor by the OS to the running processes. On some platforms it may relate to several physical processors, several processor cores, or part of one physical processor. |

Citrix-related statistical counters are collected by the Insight Savvy for OS by using the public Citrix API. Insight uses this information to correlate Citrix metrics with the processes underlying each Citrix session.
...
Citrix Client Latency (Avg) The average client latency (in seconds) for each Citrix agent. Baseline information for this counter is not available.
About entities of the Tuxedo Tier
For the Tuxedo Tier, Insight measures the response time of the following entities:• Tuxedo
- Tuxedo services
...
- Tuxedo server processes
...
- Tuxedo domains
...
- Tuxedo servers
...
- Tuxedo users
...
- Tuxedo client machines identified by the IP addresses
The response time is broken down into the following components:
...
For additional information, see the Precise Installation Guide.
About entities of the WebSphere MQ Tier
For the WebSphere MQ Tier, Insight measures the response time of the following entities:
...
WebSphere MQ Users The put user name.
NOTE To collect detailed data (message ID) or extended data (message ID, header fields, and message body), edit the parameters of the MQ process in AdminPoint by setting the required collection mode.
For additional information, see the Precise Administration Guide.
The response time is broken down into the following components:
...

About entities of the Oracle Applications Tier
For the Oracle Applications Tier, Insight measures the response time of the following entities:• Oracle
- Oracle Applications forms
...
- Oracle Applications users
...
- Oracle Applications applications
...
- Oracle Applications servers
...
- Oracle Applications client machine, identified by the IP address
...
- Oracle Applications instances, identified by the Form server listener
The response time includes the processing time of Oracle Applications client requests, such as application logic and database access.
Network time is the round-trip network time between the client and the application server. Network time and packets are not available for Oracle Applications instances, which are configured to work in Forms Listener Servlet mode.
About entities of the Other Tier
The entities displayed for the Other Tier depend on the Other Tier type (a standard regular Other Tier, or Citrix type) as defined in the Application dialog box in AdminPoint.
For the standard regular Other Tier, Insight measures the response time of the following entities:• Client

About entities of the Add-on Tier
A user or third-party vendor can collect performance data from any Tier. The Tier does not need to be supported natively by any of the Precise family of products. That means the user or third-party vendor can define an Tier: the Tier name, its entities and counters, and develop the Collector that collects this data. The Insight user interface functions the same as for all other Precise Tiers.
For an Add-on Tier, Insight can measure the following metrics for Add-on Tier activities:• Response
- Response Time. Describes the working time of the application itself to complete an activity.
...
- Statistics. Displays various statistical metrics relating to the activity (such as: message size, number of users).
...
- Executions. Represents the number of times an activity occurred in one time slice (every 15 minutes).
The response time can be broken down into various components, such as:
...
Insight displays the metrics for the Add-on Tier as Top n graphs grouped by the various entities (attributes). The Add-On Tier Collector reports the metrics for each activity. For example, if each Add-on Tier activity contains information about a Transaction name, User name and Server, then Insight will display Top Transactions, Top Users, and Top Server graphs.
For additional information, see the Precise Insight SDK User's Guide.
